To all whom it may concern: v

Be it known that I, HARRY R. LANGSLOW, a citizen of the United States,and resident of Rochester, in the county of Monroe and State of NewYork, have invented a certain new and useful Improvement in Turnstiles,of which the following is a full, clear, and exact description,reference being made to the accompanying drawings, forming part of thisspecification.

This invention relates to improvements in turnstiles and in the railingsor other barriers that coact therewith and form the passagewaysextending to and from them, the object being to improve the form,construc tion and operation of the turnstiles so as to facilitate theirmanufacture, increase their efiiciency and prolong their usefulness.

The invention consists of a combined turnstile and a barrier orbarriers, the combined devices having such peculiarities of form,construction and arrangement as are.

described below and specified in the concluding claims.

On the accompanying sheet of drawings, which illustrate the invention inthe form which is preferred for general use, and which consist of twoviews to which like reference-numerals are applied to designate likeparts in both views: Figure 1 is a plan of the apparatus; and Fig. 2, aside elevation thereof, the side shown being that indicated by the arrowbelow Fig. 1.

The turnstile shown comprises a rotary post or pillar 1, whose upperpart 2 forms a hub, and from this hub project five radial arms 3, thesearms being affixed to the hub and spaced so that they are cut lengthwiseby planes which contain the axis of the pillar and form five angles ofseventy-two degrees each.

The main railing or barrier comprises parts at and 5 which form an angleequal to two of the angles formed by the radial arms of the turnstile,the arrangement of the an gular barrier with respect to the turnstilebeing such that when the rotary part of the latter is in its normalposition the outer end of one of its arms is close to the vertex 6 ofthe angle of the barrier, and the arms which are adjacent to theaforesaid arm are parallel to the parts 41 and 5 of the barrier. Otherrailings or barriers 7 and 8 extend close to the outer ends of the arms3 which are parallel to the parts 4: and 5 of the angular barrier, whenthe rotary part of the turnstile is in its normal position, the barriers7 1 to the arms 3 for each person passing the turnstile and walking inthe passageways formed by it and the barriers described, and that livepersons can pass the turnstile with each full rotation of the rotarypart thereof. This renders it feasible to dispense with features ofconstruction which turnstiles of the common or four-armed type contain,and whose main function is to insure an angular movement of ninetydegrees by the arms each time a person passes such a turnstile, thosefeatures being in some cases springs and in othersvariously formed arms,which produce or aid in producing increments of movement that impairrather than increase the'efiiciency of the turnstiles. Therefore, themanufacture of turnstiles is facilitated by this invention, and theirefficiency is increased so that five persons instead of four can pass aturnstile with each rotation of the pillar on its axis, and withoutsubjecting the apparatus to much if any greater wear and tear than acommon turnstile gets when only four persons pass through it.

It will be understood that the invention might be embodied in combinedturnstiles and barriers differing in form from those above described,such for example as turnstiles having more than five arms and barriersadapted to coact therewith, and form suitable passageways leading to andfrom them.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent, is:

1. A combined turnstile, angular barrier, and two other barriers, theturnstile comprising a central hub and five equally spaced radial armsafiixed thereto, the angular barrier comprising parts which form anangle equal to two of the angles formed by the arms of the turnstile,and the two other barriers being parallel to said parts of the angularbarrier, the outer end of one of said arms being close to the vertex ofthe first-mentioned angle and the adjacent arms being parallel to thesides of this angle and the outer ends of these adjacent arms beingclose to said two other barriers when the rotary part of the turnstileis in its normal position.

2. A combined turnstile, angular barrier, and two other barriers, theturnstile having at least five equally spaced radial arms, the angularbarrier comprising parts which form an angle equal to two of the anglesformed by the arms of the turnstile, and the two other barriers beingparallel to. said parts of the angular barrier, the outer end of one ofsaid arms being close to the vertex of the first-mentioned angle and theadjacent arms being parallel to the sides of this angle and the outerends of these adjacent arms being close to said two other barriers whenthe rotary part of the turnstile is in its normal position.

3. A combined turnstile and angular barrier, the turnstile having atleast five equally spaced radial arms, and the barrier comprising partswhich form an angle equal to two of the angles formed by the arms of theturnstile, the outer end of one of these arms being close to the vertexof the angle of the barrier and the adjacent arms being parallel to thesides of this angle when the rotary part of the turnstile is in itsnormal position.

4. A combined turnstile and angular barrier, the turnstile comprising acentral hub and fi e equally spaced radial arms afixed thereto, and thebarrier comprising parts which form an angle equal to two of the anglesformed by the arms of the turnstile, the outer end of one of these armsbeing close to the vertex of the angle of the barrier and the adjacentarms being parallel to the sides of this angle when the rotary part ofthe turnstile is in its normal position.

A combined turnstile and angular barrier, the turnstile having at leastfive equally spaced radial arms, and the barrier compris- I ing partswhich form an angle whose vertex is close to the outer end of one of thearms at the turnstile when. the rotary part thereof is in its normalposition.

(5. A combined turnstile and angular barrier, the turnstile comprising acentral hub and live equally spaced radial arms afiixed thereto, and thebarrier comprising parts which form an angle whose vertex is close tothe outer end of one of the arms of the turnstile when the rotary partthereof is in its normal position.
